SEMAPHOR AND OTHERELEVATED SIGNAL-LIGHTS.

SPECIFICATION forming part of Letters Patent No. 347,640, dated August 17, 1886.

Application filed December 10, 1895. Serial No. 185,295. (No model.) Patented in England October 14, 1884, No. 13,595.

To all whom, it may concern:

Be it known that I, EDWARD SPENCER PI- PER, a subject of the Queen of Great Britain, residing at the city of Toronto,'in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Semaphore and other Elevated Signal- Lights, of which the following is a specification. i

The invention relates to certain new and .useful ilnprovements in semaphore and other elevated signal-lights; and it consists in the peculiar combinations and the construction and arrangements of parts, asl will be hereinafter more fully described, 'and pointed out in the claims. f

Figure 1 is a perspective view showing my semaphore arranged where two tracks cross each other. Fig. 2 is a View of myimproved semaphore, showing the outer case removed and two semaphore-arms attached. Fig. 3 is a view of my improved semaphore, showing the semaphore-arms operated from the base of the post. Fig. 4 is an enlarged detail ot' the top of Fig. 2. Fig. 5 is a detail of the outer case. Fig. 6 is a detail ofa station-signal.

In semaphores as now constructed the lamp is contained within a case supported on the end ot a vertical rod or shaft, which is caused to revolve with the movement of the semaphore-arm, so that the lights exposed on the line shall correspond with the position of the arm of the semaphore. As these movemehts are effected very rapidly, particularly when the danger-signal is thrown into position, the jar to the lamp contained within, and which moves with the revolving case, soon injures the lamp, and in some cases the light within the lamp has in this way been put out. This objection is overcome by the adoption ot' my invention.

As the details of my invention can be considerably varied in their construction and application, I have shown two or three different forms,which suggest how changes maybe made without altering the main principle of the invention. f

In Figs. l, 2, 3, and 4, Ais a hollow post, on top of' which is fixed a metal frame, B, open on its four sides, but provided with a vertical movable jacket, each side of which is provided with a glass, D, all of which may be the same color, or made of glass of contrasting col 01's. This vertical sliding jacket C is conn'eeted by the bar E to the pivoted semaphore arm F, which arm is operated by a chain, G, or in any other suitable manner. H is an or dinary hand-lamp suspended within the post A and frame B, and when in position for sig naling is immediately in front of the openings in the said frame.. As the glass surrounding the lamp II is white, a clear signal is eXhibited. Assuming the glasses D to be red, a danger-signal is exhibited the moment that the semaphore-arm F is thrown out in a horizon tal posit-ion, as it will be seen from its connection through the barE to the jacket C the said jacket will be drawn down over the open ings in front of the lamp H by the outward ac! tion ofthe arm.

Although the semaphorcarm F may be op;A erated in various ways, it is not necessary for .the object of understanding my invention to exhibit more than one plan.

As stated in the commencement ofthis specicatiomthe sliding jacket O is connected by a bar, E, to the pivoted semaphore arm F. When two semaphore-arms F are used, as shown in Figs. I, 2, and 4, I simply provide two bars, E and place and connect these bars to their respective semaphorearms on opposite sides of the pivots, so that when the jacket O moves one arm or target is thrown out to danger,7 while the other arm or target F is lowered.A Thus, when the semaphore is located as shown in Fig. I, one line or track will be closed, while the other line is indicated as being free for the passage of thetrain. On the spindle of one of the arms or targets F, I fix a sprocket-wheel, I, around which is carried a chain, G, which is made endless, and is carried round another sprocket wheel, J, either located as shown` in Fig. 1, when the semaphore is to be operated from a distance, or located, as shownin Fig. 3, when the semaphore is to be operated from the base of its post.

It will be noticed on reference to Figs. l and 2 that the chain G is carried over suitable pul leys to the sprocket-wheel J, which is located at the proper point and provided with a lever, as indicated. It will be seen by this connec- ICO tion that the simple turning of the sprocketwheel J by its lever will impart a corresponding motion to thcsprocket-whecl l,and through it the desired motion is conveyed to the semaphore arm or target F.

Fig. 5 shows an outer ease, (marked Ii in Fig. 3.) rIhis case fits round thejacket C, sufficicnt space between the outer case, K, and the inner metal frame, B, being left to allow ofthe free vertical movelnent of thc jacket C.

Fig. 5 shows a detail of the case Il. It will be noticed that an internal flange, l), is formed on the top edge of the outer case, K. This flange is intended to rest upon the top of the ease B, when the outer case, K, is slipped over it. The width of this flange holds the case K sufficicntlyfar from the frame B to leave enough space between the two to permit the f ree movement 0f the jacket (l, which, as before slated, surrounds the case B.

Fig. 3 exhibits ihc outer case, K, in position, a suitable top, L, being provided, and the cases are properly ventilated.

In Fig. 2 I show a lamp, II, lowered near the ground. In this figure it willl be seen that the lamp II is suspended on a chain or rope, M, which chain or rope )I is preferably made endless by having its other end connected to the bottom ofthe lamp, after passing over a pulley, c, located at or on the top of the frame l). From this it will be seen that the lamp II may be elevated into or lowered from the frame without the party operating it be ing required to ascend to the elevated frame B, from which the signals are given. rIhis plan, it will be seen7 affords an opportunityT of cleaning and lighting the lamp without the necessity of ascending into the elevated position in which the signal-case B is located. I may also draw attention to the fact that the jacket C, which contains the sigiialglass, is adjusted entirely independent ef the lamp;

consequently the signals may be changed witl1- out jarring or in any way affecting the burning of the lamp.

c are stops secured to the post A, for the purpose of preventing the arms F going bcyond their vertical or horizontal positions.

The jacket C is preferably made with two rows of glasses, the lower row of glasses bcing arranged to indicate one set of signals, while the second set of glasses will be exhib itcd by lowering the case C till the upper row of glasses come opposite to the lamp II.

\Vhat I clailn as my invention isl.. The post A, provided with the hollow case Il, in combi nation with thejacket C, scma phore-arm F, connected di rcctly to said jacket by the arm l), the rope G, and sprocket-wheels I and J, substantially as and for the purpose specified.

2. The post A, having the hollow case I3 scA cured to the top thereof, the jacket C, sliding on said case l, and the pivoted semaphorearm F, connected directly to said jacket by ihc bar E, in combination with the rope G, connected at one end tothe arm F, and at the other to the sprocket-wheel .Irand the stop a, secured to said post, substantially as and for the purpose specified.

The combination, with the post A, of the sliding jacket (l, the semaphore-arms F F, and the bars E, connecting said arms with the sliding jacket on opposite sides of the pivots, whereby said arms are moved si multaneously, but in opposite directions, as set forth.
